Error codeUP
ApplianceCooktop
Quick answer
UP means the cooktop is out of its normal voltage of 220-240 V. Samsung says to check the home power environment.
Model compatibility: Samsung reuses codes across series and model years, so UP may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
UP means the cooktop is out of normal voltage (220-240 V).
UP on a Samsung cooktop means it is out of its normal voltage, which Samsung gives as 220-240 V. The entry comes from Samsung’s Australian cooktop listing and applies to Australian models.
What Samsung says to check
Samsung’s instruction is short: check the home power environment. Anything beyond that belongs to a technician.
Other codes in that listing
The same Australian listing includes F0, a communication failure between the main and sub PCBs, and the underlined u, which is about cookware on induction models.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
